摘要
为探讨二维—彩色多普勒超声心动图对肺心病的诊断价值，本文对５６例经临床检查确诊为慢性肺源性心脏病的患者进行了二维—彩色多普勒检查，结果表明超声检查与心肺Ｘ线胸片检查相关性良好，诊断结果基本相符。由于心电图对肺心病的表现并不完全具有特异性，有一定的局限性，而超声弥补了心电图在这方面的不足，从而说明超声检查用于诊断肺心病更优于心电图及心肺Ｘ线胸片检查，对临床诊断肺心病特别是早期肺心病具有重要意义。
Abstract In order to explorate the value of diagnosing pulmonary heart disease by CDFI, 56 patients who have been diagnosed as chronic pulmonary heart disease were given a CDFI examination. The result shows that there is a good relationship between CDFI and heart - lung- radiograph in examing heart and Iung. The two diagnostic methods basically get the same results. In addition, we combine with CDFI the reflux rate of tricuspid valve and pulmonary valve,and pulmonary arterial pressure can be observed; as a result, a better diagnosis of the pulmonary heart disease can be made. Now we use ultrasound to prove that CDFI is much better than electrocardiogram and heart-lung radiograph examination in the diagnosis of pulmonary heart disease. CDFI has special importance in diagnosis of pulmonary heart disease, especially in diagnosis of the early pulmonary heart disease.
